Power Day 2026 is all about the unknowns of growing and the revenue we’ve yet to discover. The growth of plants is driven mainly by photosynthesis and transpiration, but have we reached the borderlines in this process or are there still undiscovered fields where we can make progress and developments? Inspired by this year’s overarching theme, Pure, Power Day 2026 invites professionals from across the horticultural value chain to explore what we don’t know yet. Instead of presenting answers, we’ll create space for open dialogue, unexpected insights, and shared learning.
As part of the 2026 edition, we’re hosting a renewed Power Day; a program designed to spark curiosity, connection, and collective discovery. The event will start with a keynote of Bosch Growers, elaborating on their expansion to the USA with strawberries, and how their unknowns, challenges and opportunities became apparent, and were tackled by themselves in the process of internationalization. Afterwards, participants of Power Day 2026 will dive deep in what the horticultural sector still must discover, to face and discuss new challenges and explore even newer opportunities. This will be done in a table-group setting, in collaboration with Marit and Peter Klapwijk, Division Q and multiple high-end moderators from the industry.
Let’s dive into the unknowns!

Tijmen van den Bosch, Moderator: Bart van Meurs, Wouter van den Bosch, Sjoerd Nieboer  , Marit Nieboer - Klapwijk, Stijn Weijns, Tiffany Tsui, Peter Klapwijk, Leo Swart, Tim Koning, Kim Schotborgh, Annet Breure

The team Rootzone Dynamics from Wageningen University & Research BU Greenhouse Horticulture focuses on investigating processes around the plant roots and in the irrigation system. Research topics: alternative growing media, microbiology, belowground phytopathology, water quality, fertigation and virology. My personal focus has been on the application of water technology to achieve a zero-emission cultivation system with optimal recirculation water quality: prevent distribution of diseases via water, removal of plant protection products from discharge water, optimization of filtration and selective ion removal. Focus is on finding technologies that have specific effects on water quality, without inhibiting plant productivity, for example for prevention of biofilm formation in irrigation lines. The role of water composition and treatment on the rootzone microbiology is another topic that still requires a lot of attention.

Mexx Holweg is a researcher specializing in controlled-environment agriculture and plant physiology. Currently he is achieving his PhD in Horticulture and Product Physiology at Wageningen University & Research. His doctoral work focused on the photobiology of medicinal cannabis, with particular emphasis on the effects of light intensity, spectral composition, and air temperature on plant morphology, photosynthesis, and the accumulation of pharmaceutical compounds.
Holweg’s research integrates morphological, physiological, and metabolic analyses to better understand how environmental parameters can optimize crop performance and secondary metabolite production. He has collaborated with both academic and industry partners to advance knowledge in cannabis cultivation under controlled conditions.

PhD Researcher

The core is focused on an affinity with technology and desiring to find optimal and new solutions. These can translate to incorporating new designs on existing systems as well as presenting new innovations to optimize processes. Designing new projects where complex and multi-layered iterative processes form obstacles have proven to hold my interest and are considered a welcome challenge.
As a research and development engineer I’ve been focused on climate and energy and improving the supporting systems in horticulture. With the vision that a stronger market benefits all, the market for horticultural projects is far from saturated. In this, optimizing our ecological footprint, the sustainability of projects on both the resource and finance sides and ensuring fresh and healthy products leave the site, are an on-going and long-term challenge for us all.
